350-501 MPLS and Segment Routing Practice Question
Which THREE steps are required when configuring MPLS L3VPN on a PE router? (Choose three.)
⚠ Common exam trap
Cisco often tests the distinction between configuring route-target values directly under the VRF versus using a route-map; candidates mistakenly think a route-map is required for RT import/export, but route-maps are only used for advanced filtering or attribute modification, not for setting the RT values themselves.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a VRF definition
Creating a VRF definition on the PE router is required to separate customer routing tables and forwarding instances in an MPLS L3VPN. The VRF provides the logical isolation needed to keep each customer's routes and traffic distinct, and it is the foundation for associating interfaces, route targets, and VRF-specific routing processes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure BGP on the CE router to advertise routes to PE
Why it's wrong here
CE configuration is not part of PE configuration steps.
- ✓
Create a VRF definition
Why this is correct
The VRF must be created on the PE.
- ✓
Configure BGP address-family ipv4 vrf to exchange VPN routes
Why this is correct
BGP with VPNv4 or VPNv6 address-family is needed to distribute VPN routes.
- ✗
Configure route-target import/export using route-map
Why it's wrong here
Route-target is configured under the VRF, not necessarily via route-map; it's a separate configuration step.
- ✓
Assign the customer-facing interface to the VRF
Why this is correct
The interface connecting to CE must be in the VRF.
